TMUX112x 2-Channel Precision Switches
Texas Instruments TMUX112x 2-Channel Precision Switches are precision complementary metal-oxide semiconductor (CMOS) devices that have two independently selectable 1:1, single-pole single-throw (SPST) switches. A wide operating supply of 1.08V to 5.5V allows for use in a broad array of applications from medical equipment to industrial systems. The device supports bidirectional analogue and digital signals on the source (Sx) and drain (Dx) pins ranging from GND to VDD. The switches of the TMUX1121 are turned on with Logic 1 on the appropriate logic control inputs, while Logic 0 is required to turn on switches in the TMUX1122. The two channels of the TMUX1123 are split, with channel one supporting Logic 1, while channel two supports Logic 0. The TMUX1123 exhibits break-before-make switching, allowing the device to be used in cross-point switching applications.
